Roof mesh installation apparatus

A roof mesh installation apparatus for a mining machine includes a mesh roll carried at a dispenser at a forward position of the machine capable of unrolling mesh to be laid and bolted at a tunnel roof. A tensioning device positioned at the dispenser is capable of actuation so as to apply a pre-tension to a forward and unbolted section of mesh with the tension being applied against an already laid and rearward bolted mesh section. Accordingly, an automated roof mesh installation apparatus and method is provided.

Apparatus for controllably unfolding flexible mesh for continuous miner, and continuous miner

An apparatus for controllably unfolding a flexible mesh for a continuous miner includes a mesh roll storage rack, a height adjustment post, a mesh rolling shaft and a flexible mesh. The flexible mesh includes a mesh roll and an unfolded mesh. The mesh roll and the unfolded mesh are an integrated structure. The mesh roll is located on the mesh roll storage rack. The unfolded mesh is clamped on the mesh rolling shaft, and is pressed on a cut un-supported tunnel roof via a roof bolt. The mesh rolling shaft is rotatably connected to a top portion of the height adjustment post. The mesh roll storage rack and the height adjustment post are both mounted on the continuous miner. The mesh rolling shaft is located at a back end of the mesh roll storage rack. A limit mechanism and a damping mechanism are disposed on the mesh rolling shaft.
